Explain the contributions mary whiton calkins and inez beverly prosser made to psychology

Mary Whiton Calkins was a leading American psychologist who is best known for two things: being the first female president of the American Psychological Association and for being denied a doctoral degree at Harvard because of her gender. However, she made significant contributions to psychology that include establishing the first psychology laboratory at a women's college, inventing the paired associate technique to study memory, and developing a theory of self-psychology, which makes the self the primary focus of psychology. Inez Beverly Prosser was the first African American woman to receive a doctoral degree in psychology in the US. She studied the academic development of children in integrated and segregated schools. She also published many articles on teaching English.
